RIB-KNITTING MACHINE.

Specification of Letterslatent.

` To all whom 'it may concern.' j

Be it known that I, JOSEPH D. MonLuY, a

citizen of the United State/s, residing in. Utica, New York, haveinvented certain Im-' provements in Rib-Knitting Machines, e of whichthe following is a specification.

My invention is intended especially for use in connection withv ribknitting machines of line gage, the purpose of my invention being toprevent interference of the needles, or

ofthe latches of the needles, of one set, with the needlesgor thelatches of the needles, of the other set-,in the operation of themachine. This ob'ect I attain in the manner hereinafter setorth`,reference being had to the accompanying drawings, in' which-Figures l, 2, 3, 4, 5 and 6 represent suflicient of the operative partsof a rib knitting machine to convey a proper understanding of myinvention, the various figures showing said operative parts .indifferent positions assumed by them during the knitting operation; Fig.7 is a view of one-half of the machine, partly in top or plan view andpartly in horizontal section, through the dial cam rings; Fig. 8 is aninside elevation showing one set of cams of the cylinder cam ringdeveloped in a flat plane, and Figs. 9 and 10 are views similar to Fig.4, but illustrating modifications of my invention.

My invention is equally applicable to straight machines or Ito circularmachines but in the accompanying drawing, I have illustrated it inconnection with a circular machine.

Referring first to Figs. l to 6 of the draw'- ings, l represents part ofthe needle cylinder of the machine having vertically guided needles 2part of the needle dial having horizontally guided needles 3 part of thecylinder cam ring, and 4 part of the dial cam ring, all of these partsbeing constructed and operated in the usual manner except as to thetiming of the movements of the cylinder and dial needles, as hereinafterexplained.

The cylinder and dial may be the stationary members of the machine andthe cylinder cam ring and dial cam ring the rotating members, or thereverse construction maybe adopted, as desired. A

Mounted upon the needle cylinder l is an outer annular dial 5. in whichare radially guide loop-receiving points 6, equaling in number the dialneedles we and in line rau ially therewith and with the spaces betweenthe cylinder needles a1. These loop-receiving points are acted upon bycams carried by an annular cam ring 7 which is mountedupon the dial-5and is caused to rotate if said dial is stationary, or 'is held againstrotation if said dial has rotary movement. The loop-v receiving points 6have butts 9 which travel 'in a cam groove 10 of the ring 7, said camrate/atea oet. 1,1912.

are at this time held in the retracted posi- I tion, asshown in Fig. 1,instead of being projected, as in an ordinary rib knitting machine.,Before the cylinder needles are retracted so as to draw their stitches,the loop-receiving points 6 n are projected as shown in Fig. 2, to suchan extent thattheir inner ends occupy the spaces between `the cylinderneedles, whereby, as the latter are retracted so as to .cast theprevious stitches and draw stitches of the fresh yarn,'loops of' thelatter will be formed over the inner portions of the projected points 6,as shown in Fig. 3, in the same manner that they would have been formedover the Shanks of the dial.,

needles if the latter'had been projected in@I the ordinary manner. Theinner ends of the" loop-receiving points 6 are now raised by the actionof the cam 12, as shown in Fig. 4, the cylinder needles, by preference,rising correspondingly as there illustrated, and the dial needles areprojected so that their outer portions pass beneath the points 6, andthrough the loops of yarn carried by said points, the same movement alsoclearing the l, stitches -`on said dial needles, as shown 1n Fig. 4. Thepoints 6 are now retracted so as to castltheir loops onto the dialneedles, this retraction of the points4 being, by preference,accompanied by a downward movement of the cylinderl needles so as todraw' the transferred loops into the hooks and in front of the latchesof the partially retracted dial needles, as shown in Fig. 5, and theretraction of said dial needles then continues until they have casttheir stitches and drawn I new stitches as shown in Fig. 6, thecylinder1 needles preferably rising to permit. such draft withoutimparting undue tension to the yarn.

. In ne gage rib knitting machines in which both the cylinder and dialneedles are projected at the same time to receive the knitting yarn,diiiiculty has been experienced vbecause of the contact of the latchesot' one set of needles with those of the other set,

such contact being due either to bending of the latches themselves or totwist-ing of the needles in their guides so as to have the same effect.It will be evident, however, that when one set of the needles isprojected While the other set is retracted, this objection isetiectually overcome.r

In Fig. 2' of the drawing, 13 represents the rojecting cam for the dialneedles and 14 the retracting cam therefor, and in Fig. 8, 15 representsthe draft cam for the cylinder needles which is so constructed as topermit rise of said cylinder needles When the loopaeceiving points are`raised, as in Fig. 4, further depression ot said needles v ing points 6to the dial needles m should be eiected at such a point in the movementof the latter Y.needles that there is no likelihood of the trapping ofthe transferred loops by the closing latches of the dial needles.

j It desired, the loop-receiving portion of the point 6 `may he so highthat the dial needle can pass beneath the same Without' any lift of thepoint, as shown in Fig. 9, in which case the points will simply have tobe projected and retracted in their radial planes, the cylinder needlesbeing drawn down in the first instance only far enough to cast theirstitches and having further draft imparted to them after the loop-receiving points have been retracted and have cast their loops onto thedial needles, or on thc other hand, it the loop receivers are at oneside of the dial needles, thc cams which impart radial reciprocatingmovement to the points 6 may be eliminated, rising and falling movementonly being imparted to them by the arms 11 and 12.

In the modification shown in Fig. 10,v the loops are. formed over tixedloop receivers (ia disposed between the cylinder needles and alongsideof thc dial needles, and at'tcr the latter have been projected so thattheir hooks have passed beyond. the loops, and their vstitches havecleared the latches, the needles arc raised at their outer ends so thattheir hooks will engage thc loops when thc needles are retracted. Suchraising ot thc hooks of the dial needles may be effected by an angularpitch of the acting facesof the dial needle actuating cams, as shown inFig. 10, and if desired each dial needle may have in the rear of itsbutt a tongue such as shown in Fig. 10, which tongue is subjected topressure when the dial needles are tip ed and freed from pressure whensaid ial needles resume their normal horizontal position and the facesof the actuating cams again resume their normal vertical relation.

Various arrangements of cams may bc employed for imparting the desiredmovements to the loop-receiving points 6, such, for instance, as areshown in the Letters Patent of R. YV. Scott, No. 925,036, dated June 15,1909, for imparting movement to the web-holders, and any desired meansmay be employed for imparting tension to the knitted Web, or causing theknocking over of the stitches upon the needles.
